WATER-GATEFOR BITCHES AND CANALS.

Specification of Letters Patent.

Application filed January 22, 1912.

Patented Apr. 22, 1913.

Serial No. 672,758.

To all whom it may concern:

Be it known that I, PERRY E. BURNHAM, a citizen of the United States, and a resident of Foods Cross, in the county of Davis and the State of Utah, have invented a new and useful ater-Gate for Ditches and Canals, of which the following is a specification.

My invention relates to gates to be used in admitting the water to laterals from ditches or canals and also for the purpose of providing an outlet for water from dams, and is especially adapted for irrigation purposes; and the objects of my invention are first; to provide a gate that is water tight as nearly as maybe; second, to provide a gate that can be readily opened and closed; third, to provide a gate of such construction that although built of slight materials, it may yet have greater power of resistance to the weight and pressure of the water; and fourth, to provide a gate of such construction as to render less likely the washing away of the place of its insertion in the side of a ditch. I

I obtain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a view in elevation of the front of the gate: Fig. 2 is a vertical crosssection of the gate in position. in a canal: Fig. 3 is a view of the slide. Fig. 4 is a plan view of themechanism for locking the gate in any desired position: Fig. 5 is a side elevation of the same: Fig. 6 shows a portion of the front of the gate frame. Fig. 7 is a vertical cross-section of the bottom of the gate frame and Fig. 8 is a horizontal cross-section of the gate through zc:c in Fig. 1 showing the manner of construction thereof.

Similar letters represent similar parts throughout the several figures.

The manner of construction of my gate is such; that the gate is able to stand a great pressure of water without being swept away or damaged, the reason being that the gate is on a slant and that part of the pressure of the water is downward instead of being entirely outward and also because of the reinforcement of the sheet material of which the gate is composed, with angle irons at suitable places.

' The manner of construction of this gate is as follows :The exit pipe, 1, is fastened to the back of the gate frame as shown in Figs. 1 and 2, the two sides of which are triangular in form and the front edge of each side is bent around an angle iron; the said angle irons being attached to the said sides in the manner illustrated in Fig. 8 at 9, 9, the slide 7 resting upon the angle irons 9, 9 and being held in position by the bent over edges of 5, 5. To the bottom of the gate frame there is attached an angle iron 4 and a brace iron 2, there being a sufficient space between the brace iron 4 and the angle iron 2, to permit the sliding gate to be readily drawn up or shoved down. The front edge of the bottom of the said gate frame is bent at an angle as shown at 3 and fastened to 4, thus affording sufficient strength to supportthe sliding gate 7.

It will be readily understood from the manner of construction illustrated in Fig. 2 that the greater the pressure of water upon the sliding gate 7 the tighter the said gate will rest upon the two angle irons 9, 9 at the sides and upon the brace iron 2 at the base, thus making the gate practically watertight and at the same time rendering the slide gate comparatively easy to move. I regulate the flow of water by fastening the sliding gate 7 in any desired position by passing the handle 10 between the movable clamp 11 and the gate frame and inserting the bolt through one of the holes in the handle andin the bar 12 at 18.

In my drawings 1 is the outlet pipe.

2 is a brace iron supporting the base of the gate frame.

3 is the inturned edge of the base plate of the gate frame.

5, 5 are the sides where they are bent around the angle irons 9, 9.

6 is the space between the angle iron 9 and the flanged edge 5 of the side forming a guide for the movement of the sliding gate.

7 is. the sliding gate.

8 is a channel iron attached to the said slide gate and forming a continuation of the handle 10.

9 is an angle iron forming the support and guide for the slide 7.

10 is the extreme end of the said handle.

11 is a movable clamp for holding the said handle 10 in position.

12 is the to of the frame supporting the slide or blade 18 is a collar for the outlet pipe 1.

14, 14 are the holes in 8 for the insertion of a staple to maintain the slide or blade at any desired elevation.

15 is the bottom of the space into which the slide descends.

16 is a hole in the clamp 11 and top of frame 12 through which the curved arm of a padlock is inserted.

17 is a bolt on which clamp 11 is pivoted.

18 is a strip of strap iron fastened to the back of the contrivance at the place where the weight of the slide rests upon said back so as to support it.

'Having't-hus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a gate for ditches and canals, the combination of a gate frame comprising a substantially vertical back applicable to the outlet pipe, a bottom plate and triangular sides, the bases of said triangles being below, and their apices at the top, the oblique margins of said triangular sides being bent inward to provide guides for a sliding gate, and said gate, as set forth.

2. In a gate for ditches and canals, the

combination of a gate frame comprising back and bottom plates and triangular sides,

as set forth, and angle and brace irons reinforcing said bottom plate and'providing a seat for the gate.

3. The herein-described lock for gates of ditches comprising a stem of the gate, a
